Scientists from the University of California, Berkeley have discovered four glial cells that control the stress response and increase the worm’s lifespan. The findings are quite surprising as glial cells have always been labeled as support cells for the neurons to support learning and memory. Scientists observed several mechanisms in the roundworm C. elegans that were involved in tackling stress response and prolonging their lifespan. Moreover, another cell called glia also found to be released a hormone that boosts that eventually boosts lifespan. Researchers considered all the findings exciting and believe it could lead to the development of drugs that improve muscle health or extend a healthy human lifespan.
